Embodiment Construction

[0021]

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. figure 1 It is a block diagram showing configurations of main parts of a wireless communication system, a base station, and a wireless communication terminal in this embodiment. Such as figure 1 As shown, the wireless communication system in this embodiment includes a base station CS and wireless communication terminals T.

[0022]

In addition, although a plurality of base stations CS are installed at intervals of a certain distance, for example, in figure 1 In order to simplify the graph, only one is drawn. In addition, although the base station CS performs wireless communication with a plurality of wireless communication terminals T, in figure 1However, only one wireless communication terminal T is drawn. In addition, in the following description, the wireless communication system in this embodiment will also use Orthogonal Frequency Div...

Abstract

Provided is a wireless communication system for performing communication by using a common control channel, which can be used in a prescribed cycle by each base station, and by using a plurality of traffic channels, which can be applicably allocated to wireless communication terminals, respectively. The wireless communication terminal is provided with a channel request means for requesting individual control channel allocation to the base station through the common control channel, and a communication control means for performing control information communication by wireless connection with the individual control channel allocated from the base station. The base station is provided with a channel allocating means for allocating one of the traffic channels as the individual control channel exclusively used for the wireless communication terminal when the request of individual control channel allocation is received from the wireless communication terminal through the common control channel.

Description

technical field [0001] The invention relates to a wireless communication system, a wireless communication terminal, a base station and a wireless communication method. This application claims priority based on Japanese Patent Application No. 2006-259076 filed on September 25, 2006, and the contents thereof are cited herein. Background technique [0002] In recent years, in mobile communication, in order to meet the demand for communication speed and the demand for securing the number of users, it is desired to adopt a communication system that can specify a channel for a wide band area, and the band of the channel can be changed at high speed. As a method of realizing this, WiMAX (Worldwide Interoperability for Microwave Access: IEEE802.16 series), which adopts the OFDMA (Orthogonal Frequency Division Multiple Access) method as a multiple connection technology, is attracting attention as a next-generation broadband mobile communication system. [0003] In this WiMAX,...
